Definitions
- the present invention is concerned with coating materials.
- Non-stick materials have recently been used particularly in the field of sanitary ceramics (wash basins, toilet bowls, etc.). It is desirable per se to be able to apply or produce such coatings quickly and easily and to make them abrasion-resistant.
- a simple application can be achieved, among other things, if the coating material with an aqueous fluid is used instead of often toxic organic solvents. This increases environmental compatibility, thus reducing the requirements that are placed on coating companies for environmental reasons.
- Coatings made of fluorinated alkoxysilanes which have at least one hydrophilic group are now known, cf. U.S. Patent 5,274,159 (Pelle ⁇ te et al.).
- the silanes used there are modified with polyethylene glycol (PEG) and water-dispersible due to their hydrophilic component, although the fluorinated molecular range that is actually relevant for the coating is hydrophobic. If such a material is applied to a ceramic to be coated or another body to be coated, it must subsequently be baked. The thermally more labile polyethylene glycol decomposes The rest and the hydrophobic coating remains.
- the temperatures required for the decomposition, in particular of polyethylene glycol, are undesirably high, in particular for many non-ceramic applications, and a large amount of substance has to be removed during firing. This can lead to undesirable discolouration and charring.
- the substances are not completely stable, but decompose gradually, which leads to difficult to process oily excretions, the decomposition depending on the pH of the solution can take place within a few minutes to a maximum of a few days, but the partial decomposition Processability already drastically limited.
- silanes can be stabilized in water by adjusting a pH in the slightly acidic range.
- the sluggishness of the Si-O-Si crosslinking at the isoelectric point is used, ie typically at a pH around two to three.
- the application of this stabilization method for fluorine-modified silanes generally fails because the extremely water-repellent fluorinated groups lead to rapid agglomeration and therefore only extremely dilute solutions with a solids content of significantly less than 1% and can only be stabilized for a short time.
- Water-based fluoroalkysilane coating systems to which large amounts of alkali metal hydroxide (s) have been added, also have the autophobia effect and its disadvantages.
- the partially or perfluorinated molecules and / or other molecules provided with hydrophobic groups form or can form an ion pair with the small, thermally labile molecule (s).
- the term "pair” refers to the pairing of ions, but not only to the exact presence of exactly one positive and one negative ion. According to the invention, there is therefore a strongly polar bond.
- the ion pair or polar bond pair has a strong one
- the whole leads to a surfactant structure or surfactant-like structure, which both requires a high level of water solubility and results in good wetting of the substrates.
- the implementation of the required starting materials can take place in the water phase, but this is not mandatory. It is also possible to use a solution of the substance or substances described as a dispersing and / or emulsifying aid, for example to apply small Teflon particles using this solution.
- the ion pair formation typically takes place in the water phase; since the water solubility of the perfluorinated and / or other hydrophobic groups is low before the ion pair is formed, a small amount of a solubilizer can be added during the reaction. However, it is also conceivable to carry out a solids conversion with subsequent dissolution in water.
- reaction conditions and / or the starting substances are selected such that at least partial crosslinking of the perfluorinated or partially fluorinated and / or other hydrophobic groups can take place before application to the body to be coated.
- this leads as necessary to a high-molecular polymer that is three-dimensionally crosslinked and insoluble.
- fluoroalkylsilanes are reacted with a quaternary ammonium compound, with the alkaline pH value allowing rapid and extensive condensation of the silane molecules already in the liquid phase.
- the released silanol groups can then further crosslink and build the desired three-dimensional network.
- the solution obtained can therefore be used as a coating solution, as an emulsifying aid and also as a surfactant. After thermal compaction on a body, a coating is obtained which has, in particular, non-stick properties.
- the small, thermally unstable molecules can be removed easily and without residue after application of the water solution to a body.
- the material remaining on the body has an excellent non-stick effect against water and 01. Thanks to its high cross-linking and the good wetting of substrates, which leads to thick layers, the abrasion resistance is high.
- a coating produced proved to be transparent, colorless, had very good adhesion to metal and ceramic, and the coated body was easy to clean The resulting contact angle against water was over 90 °.
- molecules of the structure are particularly suitable Rl I R2 -M- R4 I
- R1 is in particular per- or partially fluorinated alkyls, per- or partially fluorinated cycloalkyls and / or per- or partially fluorinated aryls.
- the fluorine atoms are separated from the M in particular by an intermediate piece, in particular in the case of Si as the M atom, of at least 2 carbon atoms; (CH 2 ) 2 spacers are typical
- R2 to R4 can be identical or different. In particular, it can be e.g. around -OH; -O-alkyl; -0- cycloalkyl; -O-aryl, -Cl, -acetoxy, -oxim. Additional functional groups may be present on the O-R residues, e.g. OH; Cl; NH2 • There can be more than R2 to R4 alkyl
- Aryl and / or cycloalkyl radicals are present, these may also have additional functional groups.
- -0-SiR ⁇ R2R3 structures can result as polycondensates.
- Suitable small, thermally labile organic molecules are primarily those of the form X + Y " . Particularly suitable as Y- are OH “ , Cl “ , Br “ , S ⁇ 4 2_ etc.
- Quaternary ammonium compounds and / or phosphonium compounds are therefore preferred, specifically because of the presence of a positive charge in aqueous solution which can cause ion pair formation. Quaternary ammonium compounds also decompose at approx. 160 ° C to volatile components escaping from the layer.
- R radicals on the X + can be the same as or different from one another.
- they can be alkyl, cycloalkyl and / or aryl radicals, each with or without additional functions;
- x + can be betaines, in particular N + (CH 3 ) 3 , in particular N + (CH 3 ) 3 - CH 2 COOH.
- Suitable quaternary ammonium compounds are in particular N (CH3) 4 ⁇ H or N (C2H5) 4 ⁇ H.
- N (CH3) 4 ⁇ H or N (C2H5) 4 ⁇ H With these short organic molecular residues on the quaternary ammonium compound, there is little steric hindrance to the desired, at least partial, crosslinking of the per- or partially fluorinated, fluorinated and / or other hydrophobic groups of molecules before they are applied to the body to be coated, and moreover, the amount of organic substances to be removed becomes smaller when the organic residues are shorter. It is therefore preferred if at least some of the small thermal molecules in the organic radicals have a total of less than about 24, in particular less than 12, carbon atoms. This increases the molecular weight of the crosslinking polymer.
- non-thermally labile ion pair formers are alkali ions, especially lithium and potassium. Alkaline earth ions can also be used. NH4 + ions can also be used.
- the concentration of the small, thermally unstable molecules determines how extensively the large molecules network with one another.
- a low concentration of quaternary ammonium ions leads to further crosslinking, as does less Ste ⁇ interference, for example due to shorter organic residues on the quaternary ammonium ion, so that the molecular weight of the polymer increases in both cases.
- Ratios of 1: 5 to 50: 1 based on moles of silanes to moles of quaternary ammonium ions are preferably used with the present invention. If too much ammonium ion is added, ie if the proportion of small, thermally unstable molecules is too high, too much organic substance must be burned out of the layer.
- the fluorinated Si compound may flocculate or precipitate out, ie the per- or partially fluorinated fluorinated and / or “large” molecules provided with other hydrophobic groups in particular after they have been cross-linked no longer remain in the solution.
- the total content of organic components that have to be removed thermally from the coating is only low. It will usually be less than 15%, otherwise the material yield will be reduced. It can even be used below 5%.
- silanes especially when fluoroalkylsilanes or other fluorinated silanes are used as partially fluorinated, perfluorinated and / or with other hydrophobic groups, it is possible to add other silanes in order to optimize the coating properties for a particular application. For example, to change the haptic (the "suitability") of the surface, the degree of water and oil repellency, etc. Up to 40 minor dimethylsilane was used in a practical exemplary embodiment, which determined the chemical resistance of the finished coating Other silanes which can easily be added are methylsilanes and / or phenylsilanes as film formers and / or hard substances.
- additives and additives in particular are added can be used as a leveling agent, solvent, general paint additive, rheology additive and / or as pigments and / or dyes.
- Preferred additives are wetting agents and fluorosurfactants and fluorinated polymers to be emulsified, for example PTFE (Teflon).
- PTFE Teflon
- the fluorosurfactants improve applicability, but are expensive. Mixtures with up to 30% fluorosurfactants gave good coating results.
- the fluorinated polymers to be dispersed are advantageously used, for example, in porous materials such as bricks, non-glazed ceramics, concrete, etc., where on the one hand the abrasion resistance of the coating materials according to the invention is further increased and on the other hand the UV resistance is improved. It is also possible to obtain a quasi stochastic structure through the dispersed fluorinated polymers, which leads to a dirt-repellent, in particular at least approximately self-cleaning surface. Alternatively and / or in addition, other additives can be added to achieve a quasi-stochastic structure, in particular pyrogenic silica, dispersed layered silicates and others. It is possible to use a content of dispersed fluorinated polymers or other additives of, for example, up to 50 percent by weight. For example, up to 30% additives and auxiliaries based on the solids content can be used.
- the water-soluble coating materials are particularly important in the field of fluorinated substances, in particular of fluoroalkyl silanes, it is possible to use the principle described for other purposes and / or other fluorinated substances, for example to achieve good corrosion protection.
- the thermal decomposition can take place in particular in the case of quaternary ammonium compounds at temperatures down to about 160.degree. However, a temperature of approximately 250 ° C. for a few minutes to hours is preferred. If the body to be coated is temperature-sensitive, it can also be kept at room temperature as a thermal treatment, but with poorer results for the abrasion resistance.
- a lint-free cotton cloth is used to apply the coating. Glass plates, ceramics and enamelled steel are rubbed in with the solution until a uniform, thin film of the coating material is visible on the surface. After drying at room temperature, the coated parts are heated in an electric oven at 260 ° C. for 1 hour. After cooling, no coating is visible to the naked eye, but water and oil pearl off the coated objects.
- the contact angle against water is 92 °, against cooking oil 65 ü .
- the abrasion resistance of the coating material is tested by rubbing with commercially available scouring milk (TARNA brand). A mason sponge with a weight of 500 g is soaked with the scouring milk and guided 400 times over the coated surface. After this treatment, the contact angle against water is still 82 °, the contact angle against cooking oil is still 60 °.
- the resulting substance is also well suited for coatings and the degree of cross-linking has been shown to depend on the concentration of N ( ⁇ 3).
- Teflon and the like could be based in particular on the inclusion in the micelles.
